ACK9010

Balun Overview

The L-com ACK9010 is a passive RF balun designed to convert between unbalanced and balanced signal paths. It provides an impedance transformation from 75 Ohms to 120 Ohms, facilitating connectivity between standard coaxial systems and twisted-pair networks. The device features a BNC female bulkhead jack interface for the 75 Ohm side and a Krone IDC connector for the 120 Ohm side. Constructed with brass body and phosphorus bronze inner contacts, it utilizes PTFE insulators and Noryl molding for durability in chassis-mounted applications.

Balun Feature Summary

• Converts between 75 Ohm unbalanced and 120 Ohm balanced signal impedances
• Features BNC female bulkhead coaxial interface for secure mounting
• Incorporates Krone IDC connector for twisted-pair integration

Balun Applications

• Connecting 75 Ohm coaxial video or data lines to 120 Ohm balanced transmission media
• Chassis-mounted RF signal distribution in broadcast or industrial equipment
• Interface adaptation between coaxial infrastructure and balanced network cabling

Balun Procurement Notes

Verify that the specific unit received matches the ACK9010 designation for the 75/120 Ohm impedance conversion. Confirm the presence of both the BNC female bulkhead jack and the Krone IDC connector as these define the physical interface requirements. Ensure the application environment supports chassis mounting, as this is the specified installation method for this component.

Balun Selection Notes

Select this component when interfacing between 75 Ohm coaxial systems and 120 Ohm balanced lines is required. The BNC bulkhead interface suits panel installations where robust coaxial connection is needed. The Krone IDC termination is appropriate for structured cabling environments using compatible punch-down blocks. This balun is suitable for passive signal routing without active amplification.

Balun Part Context

This balun belongs to L-com's passive RF interconnect series, focusing on impedance matching and signal conversion. It serves as a bridge between different transmission media standards, specifically addressing the mismatch between coaxial and balanced twisted-pair architectures. The design prioritizes mechanical stability through bulkhead mounting and reliable electrical contact via phosphorus bronze components.

Balun Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must ensure exact impedance (75/120 Ohm) and connector type (BNC Female Bulkhead / Krone IDC) compatibility when sourcing alternatives.
